Yeah, there's really not much that a single 45-year old guy has in common with a 45-year old whose married with kids. Maybe on paper they may appear to have similar jobs, live in similar places, etc. but they are on vastly different life paths with completely different interests (personal, political, social, etc.).
Interesting conversations and connections are with those people who are different from yourself, not with those who share the same experience of everything.
